摘　　要：将协同通信引入自动重传请求(ARQ)协议可以显著提高ARQ协议的性能,但是协议的性能在很大程度上要取决于重传节点的选择。为了提高ARQ协议的性能,提出了一种基于模糊综合评判的协同ARQ协议,协议综合考虑了节点的位置信息、信道信息和功率信息,并据此进行模糊综合评判,以选择出最佳的重传节点。仿真结果表明,所提协同ARQ协议的性能要明显优于以往文献提出的协同ARQ协议,是一种有效的ARQ协议。The performance of automatic repeat request（ARQ） protocols can be significantly improved by introducing cooperative communication to ARQ protocols.However,the performance of the protocols depends to a great extent,on the selection of the repeat node.A fuzzy comprehensive evaluation-based cooperative ARQ protocol was proposed by introducing cooperative communication into the ARQ protocol.The protocol takes into consideration the location information,channel information and power information of the nodes,and uses fuzzy comprehensive evaluation to select the optimum repeat node.Simulation results show that the proposed cooperative ARQ protocol is obviously better than those protocols proposed before and can thus be considered to be efficient.
